SAMUEL ILXTUIA,

States, residing at f ltichlend and {State med certain new and usein Reversible irrigating irg hi chines, of which the fola. specification. invention relates to an improvement in. reversible irrigating and ditching inachines, and an object to provide a rigid means oi etmchrhent "for adjusting the scraper to either "hroiv the dirt to the right or le::'t.

A. further object a citihr ielhy, iii-thee 1o, have v is to provide means to i slipping sludewsrying dirt being;

ie scraper ding (hie resistance of the by the S021? f oogect i" to provide means the rear Wheels continually vvorh: in in the direction from which the ntiachine is inclined to slip, thus continually resisting the natural tendency of the niachine to be pushed aside by the dirt in front of the ier object is to "provide means m ailor freedom oil atrial movement (3 v cen the iorivard truclr and the scraper,

these several objects in view, my livcn'tion consists in a reach, a forward truck with which the reach has swivel conncction, e. scraper, means for reversing the latter, and looking it in position with respect to the reach, and at the rear for resisting the tendency oil the machine to slip or slide away from the dirt being invention further novel features 01" construction and conihi nations of parts which will he hereinafter described and pointed out in the claims.

In the accompanying drawingsz-Jiigurc 1 is a view in side elevation, Fig. 2 is a plan view showing the parts iii-their ncrin al position, Fig. 3 is a planvlevv showing the scraper and rear Wheels in the POSllllOIlflS sinned when throwing the dirt to one s de, Fig. l is an enlarged, longitudinal, vertical section throng'h'the niechanisi'n for locking the scraper, lg. 5 is an enlarged detail partly in section showing guiding; hi l consists in certain the operators 6 is an enlarged detail, partly in section, showing one of the rear Wheels With the lever for raising and lowering the scraper. The reach preferably consists oi two has all-cl bars 1, 1, spaced apart at the rear by casting 2, to which the rear end of the par bars are fitted as at 3, 3, at or near the center by a block l to which the parallel hars are secured by bolts, or rivets 5, 5, and the forward ends of the parallel hers have secured therein the socket plate 6 Which clamps betvveenits sections the hall 7 which projects rearwsrdly from the sleeve 8, in which the shank 9 of the forward truck 10 is pivoted, thus providing a connection Wherehy the forward truck 10 may not only he ned to the right or left, but also whereby may swivel axially with respect to the reach or vice versa. vvardly from the level of? the axle, and is provided with a clevis 12 to which draft is new ed, and the link 13 extends from the uploer end of this arm to the upper end oi the shank 9, as shown in. Figs/1, 2, and 3, The scraper 14 is secured at its center to bracket 15, and this bracket is pivotally connected to the. rear end of the casting 2, by nieanscif a stud 1G. how 1? approxiterm, as shown in mately semi-circular 2 and 3, secnreo at its ends to the grader at points equidistant can its center Oil oscillation. llhis how 1,: is provided .h orifices l8, 18, throughout the greater i t of its length, and it passes freely tl'irongh the space 19 between the upstanding ,lugs 20, 5%, oi? the hlocl: i, at which point sliding bolt 21 operatine' through orifices 22, 22, is arranged to enter the holes 18., in registry therewith, vvherehy to lock the scraper in the desired pos'tionv A foot lever @5 is fulcrunoed at 2 Willi 111 easy reach of loot, when occupying the drivers seat 25; and a link 26 connects the forward end of this foot lever with. the locking hcltQl. A spring 2'7! normally holds this foot lever in an elevated position with the bolt 21 thrown forward, as shown in 45, or restingagainst the solid portion oi the how, in "position to pass into one of the holes 18, as soon as the latter 'isitnrned in position therefor. To remove the bolt 21, therefore, pressure is applied upon the :loot lever. In this Way, a very simple means isprovided for locking the scraper the desired angle,

[in arm 11 extends upthe change in angle being effected by swinging the reach to the provided with the usual latch is pivotally Elli connected as at 31, with each of said segments, and each of these levers carries a stem 32, and a wheel 33 is 'journaled to the rear end of each of said stems 32. It is obvious that the swinging of the lever forward or rearward, lowers or raises the scraper, and determines the depth of cut. To assist in'rcsisting the tendency of the wheels 33, 33, to slide laterally, these wheels are provided with circumferential flanges 34, which. cut into the ground and counteract the tendency of the wheels to slide. its a further means of preventing sliding and skidding, the runner 35 is provided, This is pivoted at its forward end as at 36 tov the arm 37, and its rear end is raised or lowered through the medium of a hand lever 38, fulcrumed on the rear of the scraper 1d, and the link 39 extending to the runner 35. The runner 35 is provided with several holes 40, 40,- one of which is to re ceive pin or bolt ll, according to the vertical adjustment of the runner. The arm 37 which supports the runner is pivotally connected at its forward end to the rear of the scraper as at 42, and from the rear end of this arm, braces 43, 43, extend in opposite directions to a connecting bar 48, which extends across from one segment 28 to the other. The connecting bar 48 which may be used or not has a stud lQ which extends into a slot 50 in the rear end of casing 2, to afford additional support when the scraper is in a position at right-angles to the line'of draft, as shown in Fig. 2 the slot extending longitudinally of the casting, and permitting the stud forward and rearward play therein. Two additional rods 51, 51, extend from the segment 28 to the rear end of the casting, where the latter is provided with a series of holes 53, 53, to which the inner ends of the rods 51, 51, are adjustably connected by bolts or similar means 545, 54-. The" purpose of the bar 48, and the rods 51, 51, is to shift and regulate the direction of the rear wheels 34, 3d, and the runner 35, they being turned simultaneously with the adjustment of the scraper as illustrated in Fig. 3, into a position of resistance to the tendency of the scraper to yield to and slide away from the dirt being moved thereby. In other words, the two wheels and runner cotiperate to hold the scraper steadfastly to its work. When it is desired to shift the wheels 34l34, the stud. 49 is removed from slot 50, and the bar 48 may also be removed, as shown in Fig. 0.

It is'understood that the direction of the wheels and runner are changed by shifting the inner ends of the rods 51, 51, to difierent holes 53 in the casting 2, as in this way the circle is shortened or lengthened, and the angle of the wheels is correspondingly varied.

It is evident that more or less slight changes might be resorted to in the form and arrangement of the several parts .described without departing from the spirit and scope of my invention, and hence I do not wish to limit myself to the exact construction. herein set forth, but

l-laving fully described iny invention, what I claim as new and desire to secure by Letters Patent, is I 1. The combination with a reach, a scraper hinged thereto, and wheels carried by the scraper, of a runner carried by the scraper and connected with the, said wheels, and means connecting the wheels with the rear end of the reach, whereby the position of the wheels and runner varies with the position of the reach and scraper with respect to each other.
